VIRAL VIDEO: North Carolina student is only one from school to participate in Walkout day

A tweet from a local student on National Walkout Day has gone viral because of the number of people who participated in walking out with him -- zero.

Justin Blackman walked out of class at Wilson Preparatory Academy on Wednesday, as did students all over the country, to protest gun violence after last month's mass shooting at a Florida high school that killed 17 people.

But when Blackman got outside of his school, he realized he was the only one participating.

He posted a video on Twitter, saying: "It's National Walk Out Day and I'm the only one at my school out here."
